The steam engine was utilized in a variety of industrial situations, including mining, where the earliest engines were used to pump water from deep workings. Early mills were powered by water, but with the use of a steam engine, a factory could be built anywhere, not only near water. The engine also could be used to power machinery such as saws and drills without having to transport it over long distances.
As well as powering machinery, steam engines were used as a source of energy for tools such as plows and harrows. They could also be used to drive equipment such as hoists and pumps without human intervention. In fact, many early factories used their steam engines as a form of automatic production line - one engine providing the power for as many as 24 hand-operated lathes at one time!
The need for efficient ways to produce iron brought about the development of steam technology. By the late 1700's, engineers had come up with several designs for small steam engines that were capable of powering various machines. One such engine, invented by Thomas Newcomen, was particularly effective in pumping water out of mines because it did not require any moving parts except for an air pump. This type of engine would remain the most common form of machine tool for many years after its introduction because it was so easy to operate and maintain.
The introduction of steam engines increased productivity and technology, allowing for the development of smaller and more powerful engines. These new engines could be used in many different applications, including manufacturing. One application of steam engines in manufacturing was to run machinery directly from the engine. This method of powering equipment changed the way factories were built. Before the advent of steam engines, large areas of a factory would need to be constructed before any production could begin. After the introduction of steam engines, most factories had all their machinery located in one building. This reduction in size helped them grow faster and put more equipment in less space.
Another advantage of using steam engines to power machinery is that it allows for automatic operation. Before this time, all machinery needed someone to watch it day and night to make sure it wasn't being damaged. With the use of steam engines, most pieces of equipment will run themselves without anyone having to stay up late at night or travel across countries to get their work done.
Finally, the use of steam engines allowed for more variety in manufacturing products. Before this time, people wanted their goods made only in certain places.
Prior to the invention of steam power, most industries and mills were powered by water, wind, horses, or men. Water was a good source of energy, but industries had to be near a river. It also supplied consistent electricity and could power enormous devices.
Water was used to drive machinery through hydraulic systems. The first hydraulic systems were built in Egypt around 5500 B.C. They included pipes and valves that today would cost millions of dollars to build. Ancient engineers knew how to use water efficiently- they just didn't have many machines to work with. There were no motors or generators back then!
The next major advancement in power technology came when the Chinese invented gunpowder about 1150. With this new explosive, people began to experiment with different ways to use it for power. Gunpowder is made out of sugar and chemicals, and when you blow up something with it, such as a cannon ball, you are actually using energy from the powder to do work.
The first machine tool, which is a type of engine, was developed in Germany around 1450. These tools were used by goldsmiths to make items more quickly and accurately than possible with a hand torch. They included a head with chisels that could be attached and removed as needed.
The next major development in engineering technology occurred when Thomas Edison invented the electric light in 1879.
Wind was useful for powering mills, but there were not enough trees near most settlements to provide enough wood for much more than basic household needs.
Steam power changed all that. With its help, industries could now be located far away from rivers, and many other types of power could also be used together with steam. For example, electricity could be generated by large magnets in a turbine using only water from any source (including seawater) and steam from any source (including coal).
The people who worked in these industries were called "steammen". They usually came from poor families who would travel to where work was available. This often meant going very far from their home countries. The Chinese are still known as "coolies" today because that is how they described those who went to work in British-owned factories in India. The Indian workers were called "Lascars" which means sailors in English. There were also "kelots", or Cambodian slaves, who worked in French camps on the Mekong River.
In Scotland, the first steam engines were built around 1760. They were used to drive mill wheels and pumps at mines.
